Courtney is making regular observations of the growth rate of kudzu vines on a ditch in her neighborhood. She isolated and tagge

d five tendrils of the vine, and takes weekly cumulative measurements for a year. A portion of her results are shown below. What issue with her data does Courtney need to resolve?

Hello. You forgot the results of Courtney's observations. The observations are:

"Tendril # Week 1 Week 3 Week 6

1 1.2 cm 5.9 in 1.2 ft

2 2.0 cm 4.8 in 0.98 ft

3 0.8 cm 3.2 in 0.55 ft

4 0.2 cm 1.6 in 0.35 ft

5 1.5 cm 4.3 in 1.01 ft"

Answer:

Curtney's data show inconsistent units of measure.

Explanation:

Measurement units are ways of representing great physics such as speed, size, time, quantity, weight, among others. These units serve to quantify the matter and allow observations to be made.

It is important to note that the same units of measurement must be evaluated in the same experiment. For example, if we want to evaluate how much a plant can grow in 3 weeks, we have to evaluate the same unit of measure each week. If in the first week we evaluate the growth in centimeters, we have to evaluate the growth in the next weeks also in centimeters.

Courtney did not do this, and assessed the growth of the plants each week with different units of measure, which left her data inconsistent.

harkovskaia [24]

Answer:

The correct answer is C.

Explanation:

In the question, it is stated that the woman is heterozygous, which means she posseses both the dominant allele and the recessive allele (A and a). So taking this information into account, she can produce eggs given with the option C (Aa) which include both the dominant and recessive alleles.

I hope this answer helps.

Which is not a compound?<br> 8H2<br> H2O<br> 6CaO<br> 5HCl
poizon [28]
8H2. The actual equation doesn't make sense for 8H2. This is because in compounds it always says the number of atoms after the element symbol, but in this case, there is an 8 before it. This means that it isn't a compound.

An ecosystem has 150 organisms of 15 different species. What is the biodiversity index of this ecosystem?
iren2701 [21]

Answer:

0.1

Explanation:

To calculate this, scientists use a formula called the biodiversity index in order to describe how much are the species of a given area diverse. It is calculated by taking the number of species in the area and divided by the total number of individuals in that area. This gives us the biodiversity index.

In this example, there are 15 species in an area and we divide that by 150 organisms to get a 0.1 biodiversity index.

Do you think Peacocks would be in Hardy-Weinberg Equilibrium? Why or why not?
Slav-nsk [51]

Peacocks would not be in Hardy-Weinberg Equilibrium

Explanation:

This can be justified by the mating patterns of the female peacocks. They do not choose their mates randomly but look out specifically for bright attractive plumage in their male partners and then select them.

Hardy-Weinberg's Equilibrium of evolution mechanism was based on facts like random mating, no natural selection,  mutation, absence of gene flow, and infinite population size.

They stated that organisms mate randomly with each other without any specific or a particular preference in the phenotypes of their opposite mates
